UVA815紫书例题FLOOD

这个题思路还是比较好想的，

1主要是输出坑了我一段时间，

2在使用sort函数的时候没有注意自己是从1开始计数的时候也出现了bug。

# include

using namespace std;
int a[10000];
int main(void)
{
	int m, n;
	double flood;
	int high;
	int kase = 0;
	while ((cin >> m >> n) && (m||n))
	{
		memset(a, 0, sizeof(a));
		int num = m * n;
		for (int i = 1; i <= num; i++)
		{

			cin >> high;
			a[i] = high;
		}
		sort(a+1, a + num+1);
		//for (int i = 1; i <= num; i++)
		//	cout << a[i] << endl;
		cin >> flood;
		int x = a[1];
		int high_flood=1;
		int i = 2;
		int square_change=1;
		while (flood > 0)
		{
			while ((a[i] <= x)&&num>=i)
			{
				i++;
				square_change++;
			}
			flood -= (double)(square_change*100);
			x++;
		}
		flood += (double)square_change * 100;
		double s = flood / 100 / square_change;
		double end = (double)(x - 1) + s;
		double z=((double)square_change*100 / num);
		printf("Region %dn", ++kase);
		printf("Water level is %.2lf meters.n", end);
		printf("%.2lf", z);
		cout << " percent of the region is under water." << endl<
